Cellulose fibre: lai self process

For self protection fiber quality in the production process and production capacity

Regenerated cellulose fiber, rayon fiber) preparation method is the modification of wood pulp fiber, and the dissolved solution to made into fine fibers.

Common rayon fiber with viscose fiber, acetate fiber and lyocell.

Lai self benefit from its smoothness and excellent wet strength and commonly used in industrial application.

How to produce, sell?

Lai self is to put the wood pulp dissolved in N - methyl morpholine N - oxide (NMMO) made in the organic solvent.In this process, the concentration of the solution and temperature plays an important role, for example, if the moisture content is too high (over 15%), and will not be able to dissolve cellulose.The solution by 50-60% of the initial preparation, NMMO then dissolve in heating type container NMMO for enrichment of evaporation, water and cellulose proportion of about 76: "concentrate.

Concentrate after filtration was taken to dry jet wet spinning process, and in this process through a spinneret extrusion to form a continuous filament.After the fiber after washing, drying and cutting, made the final lyocell.

Visa K - PATENTS^®Online refractometer in cernet production process of continuous monitoring in bulk and the concentration of the solvent, thus improve the production efficiency, improve the quality of fiber.
